Echocardiography

Pressure-Volume Loop — Series: #1–2

👉Pressure-volume loops illustrate ventricular mechanics through changes in preload, compliance, contractility, and afterload.
👉ESPVR and EDPVR define systolic and diastolic properties, while arterial elastance (Ea) reflects afterload.

Evaluación ecocardiográfica de la función diastólica del VI en el adulto. 📄Diagnostics 2026. 💯
🟠La valoración diastólica del VI sigue siendo un pilar de la ecocardiografía integral. No solo estima presiones de llenado, sino que es clave en el estudio de la IC FEVI preservada.
🔎 Enfoque actual multiparamétrico➡️ No existe un solo parámetro definitivo. La recomendación es integrar mediciones “clásicas” + técnicas avanzadas, adaptadas al contexto clínico y comorbilidades. 🤔⤵️
🟠Parámetros primarios:
▪️Flujo mitral (E, A, E/A, DT).
▪️Doppler tisular (e’, E/e’).
▪️Flujo venoso pulmonar (S, D, ar).
▪️TR e IVRT.
▪️Volumen auricular izquierdo indexado (LAVi).
▪️GLS del VI.
⚠️Disfunción si: E/e’ >14, LAVi >34 ml/m², TR elevada (>2.8 m/s) y e’ reducido orientan a ⤴️presiones de llenado.
🟠Técnicas avanzadas:
▪️Strain auricular (LARS)➡️ fuerte valor pronóstico en FE preservada.
▪️Myocardial Work (MW)➡️ puede aportar información indirecta sobre disfunción diastólica.
▪️Time-Harmonic Elastography (THE)➡️ nueva herramienta para rigidez miocárdica.
⚠️Limitaciones relevantes: edad, carga, arritmias, ventana acústica, variabilidad inter-vendor y dependencia del operador siguen siendo retos importantes.

1/n We are excited to announce EchoPrime – the first echocardiography AI model capable of evaluating a full transthoracic echocardiogram study, identify the most relevant videos, and produce a comprehensive interpretation!

Great work lead by @milos_ai, EchoPrime is the largest and most complex #echofirst AI model yet, trained on 10x the data of existing models.

Expanded dTGA and Morphology sections to include schematics + more information on great-vessels configuration. You will find my ppt on d-TGA that I will be giving July 9 at Phoenix Children's Hemodynamics and CHD Bootcamp.
